Briefs: Compressing videos will only do good whether you work on YouTube, FaceBook, Twitter or website. Read differences between compressed videos & uncompressed videos. Also, we've rounded up 6 best free video compressors, so that you can compress a video easily.

When a video fails to load or can't be played on a browser, uncompressed video can be a reason. You can troubleshoot the issue by compressing the video.

Part 1: Uncompressed Videos VS Compressed Videos

When uncompressed video uses up PC resources, PC will get stuck!

Tip: Uncompressed videos use normal algorithm to store all pieces of visual & audio information (piece by piece without sorting, and there can be repeated messages to ensure a piece of message is correct). Because of that, an uncompressed video may take up massive PC resources (i.e., memory and space). It's no good news to both servers(website host machines) and end-users(PCs).

Uncompressed Videos Cons:

• Uncompressed video storage wastes bandwidth.
• Uncompressed videos take more memory & space.

Q&A: Why are uncompressed videos slow or failed to load? - Besides that uncompressed video file size is large, transfering uncompressed video speed is much slower. (2 factors determines message-transferring efficiency: a)The order of message sending/receiving, b)How many messages are sent/received each time. Uncompressed videos have no edge on these sides.)

Compressed Videos Pros:

• Your video will load faster, which means a better user experience and engagement.
• Compressed videos are more platform-friendly, i.e., friendly to YouTube, Tiktok and Instagram.
